1:20.3 Scale Narrow Guage 2-6-0 Mogul Steam Loco Problem

[Old Dragoon]

Purchased this loco (81495) and attempted to run it on my track. It runs great on straight track, but when it rounds a curve it binds and stops. Upon further examination, I noticed that unlike all of my other locos, this one had two downward facing pins inside the middle drive wheels which ride inside of both track rails. I believe these pins are causing the binding and therefore stopping the loco. I also believe, according to the brochure, that these have something to do with the loco's conductivity. Does anyone know how I can remedy this situation? Thank you.
